Installing transmission: to install transmission and t-case as a unit or separately?

Im getting ready to put my transmission back in and was wondering which would be easier? To install the transmission first then put the transfer case on or to install them as a unit?
While taking it out i removed both as a unit and it was fairly awkward.

Also if anyone has access to jeep part numbers im looking for the two reverse torques bolts that hold the top of the transmission bell housing to the engine block. I stripped one while removing the trans. (might replace with regular hex head instead of replacing with reverse torques)

I've never done a TJ, but I've done a dozen or so other 4x4s and together was far easier.
Never tried it without a transmission jack. You can rent a transmission jack for cheap, save you dropping heavy stuff on your head.
